find the inverse of
\n" ); document.write( "y = exp2 (x-7) + 1
\n" ); document.write( "====
\n" ); document.write( "1st: Interchange x and y:
\n" ); document.write( "x = e^[2y-14] +1\r
\n" ); document.write( "\n" ); document.write( "---
\n" ); document.write( "e^(2y-14) = x-1
\n" ); document.write( "---
\n" ); document.write( "Take the ln of both sides:
\n" ); document.write( "(2y-14) = ln(x-1)
\n" ); document.write( "---
\n" ); document.write( "2y = ln(x-1)+14
\n" ); document.write( "y = (1/2)[ln(x+1)+14]
\n" ); document.write( "=========================
